given as much air as possible. It is well to bring the 

 Ericas out of the greenhouse as early in the spring as 

 possible. The pots should be plunged in a good situation, 

 where plenty of air and sunlight can be had. They should 

 be wintered in a greenhouse extremely well ventilated, 

 and a temperature not higher than from 40° to 45° P. 

 When in bud the plants should not be allowed to dry out 

 too much. Once would be enough to cause the loss of 

 all the buds. Very often the Heaths are attacked by a 

 disease similar to miltlew. ranscd l)y an excess of hu-

1. c4mea, Linn. {JS. herbdcea, Linn.). Height 6 in.: 

 Ivs. in 4's : inflorescence lateral : corolla broadly bell- 

 shaped: anthers exserted : ovary glabrous. Mar.-May. 

 Alps. L.B.C. 15:1452. B.M. 11. Gn. 54:1177 (a charm- 

 ing picture). The bright rosy-fld. form is the best and 

 most striking. There are pale red and pure white varie- 

 ties. The most popular of all hardy Ericas. Very easily 

 prop, by division. We should try F. Mediterranea, var. 

 hybrida, Hort., said to be a cross with F. camea, and in 

 England thriving almost as well in loam as in peat. See 

 Gn. 55, p. 125, and 54, p. 262. 



2. v4gans, Linn. Cornish HE.iTH. Lvs. in4's or 5's: 

 sepals small, ovate, obtuse ; corolla ovate-bell-shaped; 

 anthers ovate-oblong, 2-parted, exserted : ovary not 

 hairy. W. Eu. and Medit. - Pis. pale purplish red. 

 Grows 3-4 ft. in England; 1 ft. with J. W. Manning, 

 Reading, Mass. Var. diba has white fls. Var. capit^ta, 

 grows i-2 ft. high with Meehan at Gerraantown, Pa., 

 and has "small whitish fls. with a purplish tip."

3. stricta, Don. Corsicajt Heath. Lvs. in 4's, a little 

 more erect than in Nos. 3 and 5 : sepals lanceolate, ob- 

 tuse ; corolla ovoid-oblong, narrowed at the throat ; an- 

 thers awl-shaped or awned, included : ovary densely 

 covered with long, rough hairs. Corsica.— Attains 4 ft. 

 in England, but grows 1-2 ft. high with Meehan, at Ger- 

 mantown, Pa. Branches strict, rigid.

 Watson thinks it may be a wintcr-Howt-ring form of F. 

 perspiciia, figured in L.B.C. 2:1U2 and 18:1778 as F. 

 Linnaana. Pis. rosy pink, tipi.tnl white. Var. Alba has 

 white tls. With L. Dupuy, Wbitestone, L. I., it flowers 

 in Sept. G.P. 5:137. Gn. 4I:85I>. H. D. Darlington 

 says it is very distinct from F. perspicua.
